FRANK MGMILLAN, OF GLENELLYN, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, T0

NATIONAL DROP HEAD PROJECTOR COMPANY, OF FOND DU LAC, WISCONSIN, A COR- PORATION OF WISCONSIN MOTION-PICTURE MACHINE.

Application filed July 13, 1918, Serial No. 244,707. Renewed May 14, 1919.

To all whom it may concern:

Be it known that I, FRANK MCMILLAN, a citizen of th United States of America, and a resident of .Glenellyn, in the county of Dupage, State of Illinois, have invented certain new and useful Improvements in Motion-Picture Machines, of which the following is a specification.

This invention relates to the portable type of motion picture machines and has for its 0 ect:

To provide a simple and substantial structural formation and association of the inclosing casing and film reel magazines adapted to provide a rigid, light and substantial structure adapted to support the different motion picture mechanisms and parts in proper relation, and afford the re-v quired features of conpactness, strength and lightness required forfconvenience in transporting the machine from place to place, all as will hereinafter mor fully appear.

In the accompanying drawings Figure 1 is a side elevation illustrating the general arrangement of parts in the present improvement, the inclosing casing and other parts being shown in section.

Fig. 2, is a transverse sectional elevation on line X 2 Fig. 1, with the middle portions of the magazines and accessories removed to show the film feeding mechanism in front of said magazines.

Fig. 3, is a detail perspective view of one of the skeleton bracing frames of the structure.

Like reference numerals indicate like parts in the several views.

Referring to the drawings, 1 designates the main inclosing casing of the machine, preferably of the rectangular shell form shown, and having a portion of its front wall formed as a separate part or section 2 and movable in relation to the main portion of the main casing. In the present structure said movable section 2 constitutes the greater part of the front portion of the casing 1, is hinged at its lower end to said casing by a hinge connection 2 as shown, andforms the supporting means for the film feeding mechanism of the machine, so that when said movable section 2 is opened on its hinged connection the film feeding mech- Specification of Letters Patent.

anism Will move therewith into a fully exposed condition convenient of access for the usual manual manipulations of the picture film required'previous to, during and subsequent to a display of the pictures of the film. In addition to the above described construction of the main casing, the rear wall thereof is formed with a central vertical opening or passage 3 adapted to receive the adjustable illuminating means hereinafter described.

2 designates a latch mechanism for holding the movable section 2 aforesaid in a closed and operative position.

4, 4 designate counterpart skeleton bracing frames,of structural metal, secured in a longitudinal direction and in transversely spaced relation in the interior of the main casing 1, and at equal distances from the longitudinal center of same. The bracing frames 4, 4 are preferably of th rectangular yoke shape shown, and are adapted to provide the required stability and strength to support the various parts and mechanisms of the machine in proper operative relation, as well as to effectively brace the Walls of the main casing 1 and permit the use of thin and light plate material in the formation of such walls.

5, 5 designate counterpart reel casings, preferably of the open ended cup form shown, with their inner and fixed ends or heads arranged in transversely spaced relation, and with the separating space corresponding with the transverse width of the aforesaid vertical rear opening or passage 3 ofthe main casing 1 to provide a central chamber or passage in the machine for the of the casing 1 and project outwardly ther'efrom to'receive the hinged doors now to be described.

6, 6 designate individual doors, preferably of a shallow cup form, hinged to the side Walls of the casing 1 and fitting over the outwardly projecting end portions of the magazines 5, 5, said cup Shape doors being provided with beaded marginal flanges 6 adapted to bear against the side walls of the casing 1, to provide a durable and substantial construction of parts.

7 designates the carrying shaft of the film supply and take-up reels of the machine, the detail construction and arrangement of which are set forth in a companion application for Letters Patent, Serial No. 244,796.

8 designates a pulley mounted on the central portion of the reel carrying shaft 7 and having operative connection with the film feeding mechanism of the machine.

9 designates the supporting frame of the film feeding and guiding mechanism of the machine, and which in the present structure is secured to and is movable with the hinged section 2 of the main casing heretofore described.

10 designates the objective of the motion picture machine, also mounted on the hinged section 2 of the main casing in proper operative relation to the film feeding and guiding means and associated light controlling means of the machine.

11 designates the primary shaft ofthe film feeding mechanism, journaled transversely in the supporting frame 9 aforesaid, and having the usual intermittent and continuous gearing connections With'the intermittent filmfeeding sprocket drum 12 and carrying shaft '13 of the light controlling shutter of the machine.

lt designates a friction 'or like driven wheel secured to the primary shaft 11, and having operative engagement with a similar driving wheel 15 carried on the forward end of a shaft 16 arranged longitudinally in the heretofore described central space of the machine.

17 designates a pulley mounted on the primary shaft 11 and having an endless belt connection 18 with the pulley 8' of the reel carrying shaft 7 aforesaid.

19, 20 designate the film supply and. film take-up sprocket drums of the machine, fixed on the respective ends of the primary shaft 11 in line with the film supply and film take-up reels-when the same are in position in the magazines 5, 5.

2'1 designates an electric or like motor by which the machine is driven, arranged in the rear and lower portion of the central space of the machine, as shown, and having gearing connection 22 with the rear end of the longitudinally arranged shaft 16 aforesaid. With the arrangement of the mechanism so far described, as the hinged section 2'of the main casing. 1 is lowered to an open position, it carries with it the film feeding and guiding mechanism to a position in which said parts, as well as the entry and exit openings of the reel magazines 5, 5 are readily accessible for the usual changes and manipulations of the picture film in changing or replacing the same.

23 designates a trackway secured longitudinally to the inner fixed wall of a magazine 5 aforesaid, and adapted to receive and guide a sliding bar 24.

25 designates an inclosing casing containing the condenser lens of the light system of the machine, and secured to the rear end of the sliding bar 2 1 so as to be adjustable therewith.

26 designates a lamp house or casing secured to the rear end of the lens containing casing 25 aforesaid, by vertically arranged inter-engaging flanges 27, so as to be capable of independent vertical adjustment in relation to said casing 25, in efiecting a proper adjustment of the machine for actual use.

The detail construction and arrangement of the condenser lens casing and lamp house and the adjustments of the same above described, are set forth in detail and claimed in a companion rap lication for Letters Patent, Serial No. 244, 08, and no claim thereto is made in the present case. I
